Composite image using observations from infrared, visible, and ultraviolet wavelengths of the area around the Jellyfish Nebula. The ultraviolet observation is taken by Swift and shown in violet. On a mottled reddish background speckled with stars, a yellow haze of gas at center left traces out a dome-shaped structure from which curving tendrils extend toward the lower right. Blue and red filaments trace a ring around the dome’s base. A violet arc stretches right to left just above the center of the image, and irregular orange gas clouds become thicker toward the upper left.
